Abstract

A frameless door window regulator adjustment assembly comprises upper and lower guide rail attachments for precise glass positioning. The lower guide rail attachment, mounted on the door inner panel, includes a guide rail bracket and a window regulator bracket sandwiching a cam plate. The guide rail bracket has a slot and a stud bolt, aligned with the camshaft hole and slot on the window regulator bracket, respectively. The cam plate features an anti-rotation hole and a cam plate slot, aligned with the slot and the stud bolt on the guide rail bracket and the camshaft hole and slot on the window regulator bracket, respectably. The camshaft connects the window regulator bracket and the cam plate, enabling controlled movement of the guide rail bracket and glass tilting. The camshaft and cam plate are non-rotatably connected and may be made of durable materials like steel or die-casting, and may be a one-piece part. Fasteners secure the camshaft and cam plate to the guide rail bracket, simplifying assembly.
